摘要

最小和最大流速（Qmin，Qmax）限制了电喷射（锥形喷射模式）的操作窗口。文献并没有给出一个通用的、经过实验验证的、可用的公式。我们用基础物理学和曲线拟合推导了低/中高粘度牛顿液体的Qmin和Qo（=εoγρK）之间的关系。该公式得到了自己的实验和文献数据的证实。根据公式Qmin，可以通过仅测量待喷射液体的某些性质来获得。Qmax，很难解决。经验结果和实验数据表明Qmax/Qmin的比率在几十到几百之间。

On the minimum and maximum flowrate of electrospraying: A practical approach, based on fundamentals, for design purposes

The minimum and maximum flow rates (Q_min, Q_max) limit the operational window of electrospraying (cone-jet mode). Literature does not give a general, experimentally proven, useable formula. We derived with fundamental physics and curve fitting a relation between Q_min and Q_o $(= \frac{ε_{o} γ}{ρ K})$ , for Newtonian liquids with low/moderately high viscosities. The formula is corroborated by own experiments and data from literature. With the formula Q_min can be obtained by only measuring some properties of the liquid to be sprayed. Q_max, is difficult to address. An empirical result and experimental data indicate a ratio of Q_max/Q_min between some tens and some hundreds.
